Multi-purpose dental applicator

ABSTRACT

A multi-purpose dental applicator including a handle and an interchangeable removable member which can be a yoke supporting a length of dental floss, a toothbrush, a spiral wound wire tooth cleaning brush, a rubber tip gum massager, or a length of abrasive tape. The handle has an elongated shank for gripping purposes and a head piece having a receiving cavity for receiving the shank of the interchangeable removable member. The handle further incorporates threads on the outer surface of the head surrounding the receiving cavity. In the preferred embodiment, the receiving cavity is an opening extending into the body of the head in a generally inverted frustum shaped configuration which then extends into a spherical shaped cavity and thereafter extends into an arcuate section having the circumferential length of approximately twenty degrees to either side of the vertical or longitudinal axis of the head. This cavity is designed to receive a specially designed shank which design is common to all of the interchangeable removable members. The handle further comprises a slidable and threaded collar which can be slid onto and screwed around the opening to tighten the interchangeable removable member to the handle.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to the field of dental apparatus used by the consumer such as dental floss, toothbrushes, spiral wire tooth cleaning brushes, and dental massaging rubber tips. More particularly, the present invention relates to the field of dental flossing apparatus which are designed to hold a length of dental floss in a given manner such that it can be used to clean the interstices between adjacent teeth. The present invention also relates to an interchangeable multi-purpose applicator which can retain a dental floss apparatus, a toothbrush, a wire tooth cleaning brush, and a rubber gum massager.

2. Description of the Prior Art

The inventor is also the inventor of co-pending patent application Ser. No. 07/420,424 for Dental Flossing Apparatus which will issue as U.S. Pat. No. 4,920,992 on May 1, 1990 for Dental Flossing Apparatus. Through prosecution of that patent application, the inventor has become aware of the following prior art. In most conventional practice, an individual using dental floss to clean the interstices between the user's teeth unwraps a length of dental floss from its container and wraps one end of the floss around a finger of one hand and wraps the opposite end of the floss around a finger of the other hand and thereafter holds the length of floss taut between the two fingers so that it can be inserted between two adjacent teeth and moved back and forth to clean the area., One problem with this method is that a large amount of floss is used. Second, it is sometimes difficult to reach back areas of the mouth when holding the length of floss in this manner.

In some instances, attempts have been made to provide devices for holding the length of floss, which usually takes the form of a yoke across which a portion of the floss is trained while the opposite ends are wrapped about the projecting legs of the yoke. The entire apparatus is then placed in the user's mouth while the fingers manipulate the device between the teeth for cleaning. Several prior art patents disclose variations on this concept. They are as follows:

1. U.S. Pat. No. 3,927,686 issued in 1975 to Zambito for "Dental Floss Holder".

2. U.S. Pat. No. 3,631,869 issued in 1972 to Espinosa for "Dental Floss Holder".

3. U.S. Pat. No. 3,847,168 issued in 1974 to Schlegel for "Tooth Cleaning Appliance".

4. U.S. Pat. No. 2,837,098 issued to 1958 to Sorboro for "Dental Floss Holder And Dispenser".

5. U.S. Pat. No. 1,480,101 issued in 1924 to Ogden for "Dental Floss Appliance".

6. U.S. Pat. No. 2,187,899 issued in 1940 to Henne for "Dental Floss Throw-Away Unit".

7. U.S. Pat. No. 1,346,125 issued in 1982 to Hasbrook for "Sanitary Teeth Cleaner".

8. U.S. Pat. No. 4,319,595 issued in 1982 to Ulrich for "Dental Care Unit".

The apparatus disclosed in Zambito has several disadvantages. Besides being expensive to manufacture, the method of attaching the head holding the floss to the handle cannot provide a firm and secure grip on the head. As a result, when used with vigorous action as is common when flossing, it is possible for the head to come loose and fall into the user's throat and cause the user to choke. In addition, the device does not provide a universal choice of positioning the head orientation and therefore certain parts of the mouth such as the back teeth may be difficult to reach and clean with this device. Further, Zambito does not provide a choice of flossing means and it is also vitally important to prevent sagging of the floss itself.

The apparatus disclosed in Espinosa also has several problems. Not enough tension can possibly be applied to the floss by this method. During flossing, the floss would sag and make the floss device useless. As with the device in Zambito, the device does not provide a universal choice of positioning the head orientation and therefore certain parts of the mouth such as the back teeth may be difficult to reach and clean with this device. In addition, this device with its many grooves, channels, indentations and other slot attachments is an expensive device to manufacture.

The apparatus disclosed in Schlegel is also an expensive and cumbersome device to manufacture and further has a complicated way for retaining the floss. The floss can easily become loose and sag making it worthless for flossing. In addition, the yoke has only one orientation, making it difficult to reach certain parts of the mouth.

The apparatus disclosed in Sorboro, Ogden, Henne, and Hasbrook also have many of the disadvantages previously discussed. The yoke holding the floss is once again in a fixed orientation making it difficult to reach certain parts of the mouth. The complicated structure is also expensive to manufacture.

The apparatus in Ulrich is a dental water pik.

Overall, the prior art embodiments of yoke apparatus which retain a length of dental floss all have in common one or more of the following defects. First, the yoke is oriented in a fixed position and cannot be adjusted to accommodate difficult locations in the mouth. Second, the device is complicated and expensive to manufacture. Third, the floss itself is not held securely and can easily sag and come loose during use, thereby making it worthless. Therefore, there is a significant need for a flossing apparatus which overcomes these defects.

There is no device known to the inventor which operates as a multipurpose apparatus to interchangeably support a dental floss device, a toothbrush, a spiral wound wire tooth cleaning brush and a rubber tip gum massager.

SUMMARY OF THE PRESENT INVENTION

The present invention relates to an improved multipurpose dental applicator comprising a handle and an interchangeable removable member which can be a yoke supporting a length of dental floss, a toothbrush, a spiral wound wire tooth cleaning brush, or a rubber tip gum massager. The handle comprises an elongated shank for gripping purposes and a head piece having a receiving means for receiving the shank of the interchangeable removable member. The handle further comprises threads on the outer surface of the head surrounding the receiving means. In the preferred embodiment, the receiving means is an opening extending into the body of the head in a generally inverted frustum shaped configuration which then extends into a spherical shaped cavity and thereafter extends into an arcuate section having the circumferential length of approximately twenty degrees to either side of the vertical or longitudinal axis of the head. This cavity is designed to receive a specially designed shank which design is common to all of the interchangeable removable members. The handle further comprises a slidable and threaded collar which can be slid onto and screwed around the opening to tighten the interchangeable removable member to the handle.

The interchangeable removable member has a similar section and a modified section for each other members. The similar section comprises an elongated shank by which the member is held in the handle. The elongated shank has proximate one end a spherical ball and an elongated stem section extending from the ball in alignment with the shank. Proximate its opposite end, the shank extends into the specific interchangeable part. In one embodiment, the part is a yoke comprising two arms for retaining a length of dental floss between them. In the preferred embodiment, the arms of the yoke are aligned at approximately thirty-five degrees to the stem section. In a second embodiment, the part is a rubber tip for massaging gums and comprises a central core shank with the rubber tip mounted on it. In the preferred embodiment, the central core shank and rubber tip are aligned at approximately thirty-five degrees to the stem section. In a third embodiment, the part is a spiral wound wire tooth cleaner comprising a central core shank and wire bristles spirally wound around the shank. In the preferred embodiment, the central core shank is aligned at approximately thirtyfive degrees to the stem section. In a fourth embodiment, the part is a toothbrush. In the preferred embodiment, the head of the toothbrush is aligned at approximately thirtyfive degrees to the stem section while the bristles extend perpendicularly to the head. With each of the four pieces, the shank terminating in a sphere with a stem extending from the sphere and aligned with the shank provides a stable means for supporting the interchangeable removable member within the head of the handle. Once the shank is placed inside the cavity in the head of the handle, the sphere can be rotated in the horizontal plane within the spherical cavity and the stem can be rocked forward and backward or from side to side within the twenty-degree arc of the cavities above and below the spherical cavity. With the preferred embodiment having the operating part set at approximately thirty-five degrees to the stem, the angle of the part relative to the handle member can be rotated from fifty-five degrees to fifteen degrees relative to the handle. Once the piece is rotated to the desire angle relative to the handle, the collar can be slid onto the threads on the outer surface of the head of the handle and threaded into place so that the shank, sphere and stem of the interchangeable removable piece can be retained securely within the handle so that it cannot possibly fall out and fall into a user's throat during use and at the same time can be oriented at the desired angle to accommodate different locations in the user's mouth.

It has been discovered, according to the present invention, that if an interchangeable removable section comprises a shank having a spherical tip and a stem extending from the spherical tip and aligned with the shank, then the interchangeable removable section can be inserted into a receiving cavity in the head of a handle and oriented at any desired orientation relative to the handle so that any desired location of the mouth can be reached by the operating portion of the interchangeable removable section.

It has further been discovered, according to the present invention, that if the handle comprises a spherical cavity with a pair of arcuate cavities located above and below the spherical cavity with the upper cavity shaped as a frustum and the lower cavity generally arcuate with both cavities having a spread of twenty-degrees relative to the vertical or longitudinal axis of the head, then the shank section of the removable interchangeable member can be inserted into the cavities such that the sphere on the shank can fit within the spherical cavity, the stem portion fits into the lower arcuate cavity and a portion of the stem rests within the upper frustum shaped cavity such that the stem can be rotated in the horizontal plane at any 360 degree orientation while the stem can also be moved to the limited arcuate distance relative to the head.

It has additionally been discovered that if the handle further comprises a slidable collar which contains securing means for tightening the shank and its sphere and stem onto the collar, then the shank can be securely tightened onto the head to prevent it for coming loose during use.

It has also been discovered, according to the present invention, that any dental device can be incorporated onto the shank of the removable interchangeable member such as a yoke containing a length of dental floss between the yoke members, a toothbrush, a spiral wire tooth cleaning brush, a rubber tip gum massager, and a yoke containing a length of abrasive tape between the yoke members.

It has additionally been discovered that if a container comprises an accommodating opening to receive a multiplicity of the interchangeable members, then the members can be kept in a sanitary condition. For example, in one embodiment, a multiplicity a yokes having a length of dental floss can be retained and subsequently discarded after use. Similarly, yokes having a length of abrasive tape can be retained and subsequently discarded after use. Other more expensive items such as the toothbrush, spiral wound wire brush and rubber tip gum massager can be retained in a sanitary manner and cleaned before being replaced in the container.

It is therefore an object of the present invention to provide a dental applicator device having a handle which can accommodate various interchangeable removable devices which each can be oriented in any desire orientation relative to the handle so that the operating portion of interchangeable removable member which may be dental floss, a toothbrush, a spiral wound wire brush, a rubber tip gum massager, or abrasive tape can reach any desired portion of the mouth.

It is a further object of the present invention to provide a dental device wherein each of the interchangeable removable members can be securely retained on the handle during use so that the removable interchangeable member cannot come loose during use and accidentally fall into the user's throat.

It is a further object of the present invention to provide a retaining means for retaining a multiplicity of each of the interchangeable removable members in a sanitary manner so that they can be used and either discarded or else washed and replaced for subsequent use.

Further novel features and other objects of the present invention will become apparent from the following detailed description, discussion and the appended claims, taken in conjunction with the drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Although specific embodiments of the invention will now be described with reference to the drawings, it should be understood that such embodiments are by way of example only and merely illustrative of but a small number of the many possible specific embodiments which can represent applications of the principles of the invention. Various changes and modifications obvious to one skilled in the art to which the invention pertains are deemed to be within the spirit, scope and contemplation of the invention as further defined in the appended claims.

Referring particularly to FIGS. 1 and 3, there is shown at 20 the specific handle of the present invention multi-purpose dental applicator. The handle 20 comprises an elongated shank section 22 and a head section 24. While the shank section is shown as cylindrical, it will be appreciated that any other design such as rectangular can also be used with the present invention. While the surface of the shank is shown as smooth, it can also include ribs for more easy gripping. The head section 24 further comprises threads 26 on its exterior surface. The upper portion of the head section 24 also comprises an internal opening 28 leading to three internal cavities. The first cavity 30 is generally in the shape of a frustum, having base opening 32 which is aligned with opening 28 in the top of the head 24 and internal surface 34. Slanted walls 36 and 38 are aligned so that there is an angle "A" between the walls and the longitudinal axis of the head 24. In the preferred embodiment, the angle "A" is approximately 20 degrees. First cavity 30 extends into second cavity 40 which is spherical. The circumference of second spherical cavity 40 is aligned with internal surface 34 of first cavity 30. Beneath spherical cavity 40 is third arcuate cavity 50 having upper surface 52 also aligned with the circumference of spherical cavity 40. The lower extremity of arcuate cavity 50 is bounded by arcuate surface 54. Slanted walls 56 and 58 are aligned so that there is an angle "B" between the walls and the longitudinal axis of the head 24. In the preferred embodiment, the angle "B" is approximately 20 degrees. As illustrated in FIG. 3, the three cavities 30, 40 and 50 are contiguous. The head section further comprises a collar 60 having internal threads 62. The collar can be rotated down from the head 24 and extend onto the neck section between shank section 22 and head section 24. In this way, the head section 24 is loosened and can accept the shank of the associated interchangeable removable member.

The present invention is primarily used with four different interchangeable removable members. One such member which is the dental flossing yoke is illustrated in place in FIGS. 1 and 2. The interchangeable removable yoke member 70 comprises an elongated shank 72 which extends into a spherical ball 74 at its lowermost tip. Extending from the spherical ball at a location diametrically opposite to the attachment point of the shank 72 is a stem 76 which is aligned with the shank 72. The assembly is designed to be accommodated within the three cavities such that the spherical ball 74 pops into the spherical cavity 40 and is rotatably retained therein. The stem 76 fits within lowermost arcuate cavity 50 while a portion of the shank 72 rests within upper frustum shaped cavity 30. Once in place, the threaded collar 60 is rotated from the neck 25 onto the threads 26 of head section 24 so that it creates a tight fit of the assembly of shank 72, spherical ball 74 and stem 76 within the head 24. In this way, the assembly is held securely within the head 24.

The opposite end of the shank 72 remote from the spherical ball 74 then extends to the operating device. The first operating device is a dental floss retaining yoke 80. The yoke 80 comprises a pair of arms 82 and 88. Arm 82 is set at a vertical angle and terminates in a rounded tip 84 at its upper end. The lower end 86 of arm 82 is formed into yoke base 96. Arm 88 is set at a vertical angle and terminates in a rounded tip 90 at its upper end. The lower end 92 of arm 88 is formed into yoke base 96. The two arms 82 and 88 extend away from each other to form a generally "V" shaped configuration. The yoke base 96 extends into shank 72. The arms 82 and 88 are aligned in the same vertical plane. As illustrated in FIG. 2, in the preferred embodiment the arms 82 and 88 and yoke 80 are aligned at an angle "C" relative to shank 72. In the preferred embodiment, the angle C is approximately 35 degrees. Stretched across the interior upper area of the yoke 80 adjacent rounded tips 84 and 90 is a piece of dental floss 100. End 102 of dental floss 100 is bonded to the rounded tip 84 of arm 82. End 104 of dental floss 100 is bonded to the rounded tip 90 of arm 88. The bonding means may be glue or other suitable adhesive which serves to bond the dental floss 100 to the tips of the arms of the yoke 80. Alternatively, the process can be provided wherein the length of dental floss 100 is directly bonded to the tips as the yoke 80 is being molded. In this way, the dental floss 100 is held taut between the tips of the arms of the yoke and therefore cannot come loose and will not sag during use. Therefore, with the shank 72, spherical ball 74 and stem 76 inserted as previously described, the yoke 80 can be oriented in any horizontal plane (plane perpendicular to the longitudinal axis of the head 24 and shank 22) and also rotated relative to the head 24 within the limits of cavities 30 and 50 until the desired orientation of the yoke 80 relative to the handle 20 is achieved. With angles A and B each being 20 degrees and angle C being 35 degrees, it will be appreciated that the orientation of the yoke 80 relative to the handle 20 will range between 15 degrees and 55 degrees. After the proper orientation is achieved, the collar 60 is tightened onto the head 24 as previously described and the apparatus is set for use. After use, the collar is loosened by being threaded off the head 24 so that it rests on neck 25 and the yoke apparatus 80 is removed.

Similarly, the remaining interchangeable removable members can be inserted and used. Referring to FIG. 4, the second interchangeable removable member is a rubber tip gum massager. The same three components are now numbered 112 for the shank, 114 for the spherical ball and 116 for the stem. The shank 112 at its location opposite from the spherical ball 114 extends into a shank 118 which in turn supports at its remote end a rubber tip gum massager 120 of conventional design. The shank 118 is preferably offset at an angle "D" relative to shank 112. In the preferred embodiment, the angle D is approximately 35 degrees. Therefore, with the shank 112, spherical ball 114 and stem 116 inserted as previously described, the rubber tip gum massager 120 can be oriented in any horizontal plane (plane perpendicular to the longitudinal axis of the head 24 and shank 22) and also rotated relative to the head 24 within the limits of cavities 30 and 50 until the desired orientation of the rubber tip gum massager 120 relative to the handle 20 is achieved. With angles A and B each being 20 degrees and angle D being 35 degrees, it will be appreciated that the orientation of the rubber tip gum massager 120 relative to the handle 20 will range between 15 degrees and 55 degrees. After the proper orientation is achieved, the collar 60 is tightened onto the head 24 as previously described and the apparatus is set for use. After use, the collar is loosened by being threaded off the head 24 so that it rests on neck 25 and the rubber tip gum massager apparatus is removed.

Referring to FIG. 5, the third interchangeable removable member is a spiral wound wire tooth cleaning brush. The same three components are now numbered 122 for the shank, 124 for the spherical ball and 126 for the stem. The shank 122 at its location opposite from the spherical ball 124 extends into a shank 128 which in turn supports along its length a spiral wound tooth cleaning brush 130. The brush 130 comprises a wire 132 which is wound in a spiral having a broader base 134 and terminating in a pointed tip 136. The shank 128 is preferably offset at an angle "E" relative to shank 122. In the preferred embodiment, the angle E is approximately 35 degrees. Therefore, with the shank 122, spherical ball 124 and stem 126 inserted as previously described, spiral wound wire tooth cleaning brush 130 can be oriented in any horizontal plane (plane perpendicular to the longitudinal axis of the head 24 and shank 22) and also rotated relative to the head 24 within the limits of cavities 30 and 50 until the desired orientation of the spiral wound wire tooth cleaning brush 130 relative to the handle 20 is achieved. With angles A and B each being 20 degrees and angle E being 35 degrees, it will be appreciated that the orientation of the spiral wound wire tooth cleaning brush 130 relative to the handle 20 will range between 15 degrees and 55 degrees. After the proper orientation is achieved, the collar 60 is tightened onto the head 24 as previously described and the apparatus is set for use. After use, the collar is loosened by being threaded off the head 24 so that it rests on neck 25 and the spiral wound wire tooth cleaning brush apparatus is removed.

Referring to FIG. 6, the fourth interchangeable removable member is a toothbrush. The same three components are now numbered 142 for the shank, 144 for the spherical ball and 146 for the stem. The shank 142 at its location opposite from the spherical ball 144 extends into a shank 148 which in turn extends into the head 150 of the toothbrush. Bristles 152 extend generally perpendicular to head 150. The shank 148 is preferably offset at an angle "F" relative to shank 142. In the preferred embodiment, the angle F is approximately 35 degrees. Therefore, with the shank 142, spherical ball 144 and stem 146 inserted as previously described, toothbrush head 150 can be oriented in any horizontal plane (plane perpendicular to the longitudinal axis of the head 24 and shank 22) and also rotated relative to the head 24 within the limits of cavities 30 and 50 until the desired orientation of the toothbrush head 150 and bristles 152 relative to the handle 20 is achieved. With angles A and B each being 20 degrees and angle F being 35 degrees, it will be appreciated that the orientation of the toothbrush head 150 relative to the handle 20 will range between 15 degrees and 55 degrees. After the proper orientation is achieved, the collar 60 is tightened onto the head 24 as previously described and the apparatus is set for use. After use, the collar is loosened by being threaded off the head 24 so that it rests on neck 25 and the toothbrush apparatus is removed.

Referring to FIG. 11, the fifth interchangeable removable member is another yoke, comparable to the device illustrated in FIGS. 1 through 3, but containing a length of abrasive tape 200 having abrasive material 210 thereon between yoke arms 82 and 88. The length of abrasive tape 200 may be affixed to the tips of the yoke arms through slots 212 and 214 in arms 82 and 88 respectively. Other conventional means may also be used to support the abrasive tape on the yoke arms. The abrasive tape can be used to scrape off stains such as coffee and tea stains between adjacent teeth. The tape 200 may also function as a tooth polishing tape.

A simple case apparatus can be used for retaining a multiplicity of a selected one of the interchange removable members. The case 160 is illustrated in FIGS. 7 through 10 and comprises a pair of parallel oppositely disposed longitudinal walls 162 and 164 and a pair of parallel oppositely disposed lateral walls 166 and 168, a bottom 170 and a top 180 which is hingably supported at one end 182 on longitudinal wall 162 so that it can be rotated to an opened position for access to the case. Longitudinal wall 162 further comprises an interior elongated shelf 186 offset by a distance from bottom 170. Longitudinal wall 164 further comprises an interior elongated shelf 188 offset by a distance from bottom 170. Removably retained on shelves 186 and 188 is a removable and interchangeable apparatus retaining member 190. The apparatus retaining member has a multiplicity of openings designed to conform to the shape of the specific interchangeable removable member being retained therein. In the case of the flossing yoke 80 or abrasive tape yoke apparatus retaining member 190, the openings 192 are generally oval as illustrated in FIG. 7. The oval configuration can also be used to accommodate the rubber tip gum massager as illustrated in FIG. 8, the spiral wound wire tooth cleaning brush as illustrated in FIG. 9 and the toothbrush as illustrated in FIG. 10. Of course, the openings 192 can also be circular or other shapes to accommodate the specific size. The openings 192 are aligned in a row so that each apparatus is separated from its adjacent apparatus and is housed within the opening well 194 so that the apparatus is retained in a safe and sanitary manner. After all of the apparatuses have been used, the apparatus retaining member 190 is discarded and a new apparatus retaining member with a full loaded of interchangeable removable member is inserted. While the illustration shows all of the same apparatus in each case, it is within the spirit and scope of the present invention to have several different interchangeable removable members in the same apparatus retaining member 190.

Defined more broadly, the present invention is a multipurpose dental applicator comprising:

a. a handle member further comprising,

(i) an elongated shank,

(ii) a throat section extending from the elongated shank and extending to a head section,
